Diagnosis Procedure

a. Turn ignition switch to LOCK.
b. Disconnect the negative battery cable.
c. Disconnect all wheel speed sensor connectors.
d. Check if the wire harnesses are worn, pierced, pinched or partially broken.
e. Look for broken, bent, protruded or corroded terminals.
f. Check if related connector pins are in good condition.

a. Turn ignition switch to LOCK.
b. Disconnect the negative battery cable.
c. Check the wheel speed sensor mounting bolt for looseness.

a. Connect X-431 3G diagnostic tester (the latest software) to Data Link Connector (DLC).
b. Drive the vehicle straight ahead, and read the data stream of each wheel speed sensor with X-431 3G

diagnostic tester.

c. Check if the data change of each wheel speed sensor matches the change of other wheel speed sensors.

a. Remove the hub assembly.
b. Check for foreign matter, missing teeth or damage on the hub ring gear.
c. Check if the hub assembly is securely installed.

a. Turn ignition switch to LOCK.
b. Disconnect the negative battery cable.
c. Disconnect the ABS control module assembly connector

E-085.

d. Disconnect the front left wheel speed sensor connector

E-060 and front right wheel speed sensor connector



E-036.

e. Disconnect the rear left wheel speed sensor connector

B-029 and rear right wheel speed sensor connector



B-009.

f. Using a digital multimeter, check for continuity between

the terminal 8 of connector E-085 and the terminal 2 of
connector E-060 to check if there is an open in the front
left wheel speed sensor signal wire according to the table
below.
Standard Condition

3

Check wheel speed sensor

Replace corresponding wheel speed
sensor

NG

4

Check hub ring gear

OK

Replace corresponding hub ring gear

NG

5

Check wire harness and connector (wheel speed sensor - ABS control module assembly)
